Hi, Goal: We are trying to calculate actual disk usage of LVM Snapshots created from a thin logical volume. Method: Currently we use thin_dump to dump metadata information of all the LVM snapshots and logical volumes. Check what are the blocks unique to the snapshot and that gives you the size of the snapshot. The problem is while one is dumping data on the snapshot the metadata information which you get from thin dump is incorrect. That is what I noticed. Sometimes the tool will fail and it will ask you to repair your lvm metadata. --- Is there a way we can have a separate tool which will give us the disk usage of a LVM Snapshot. Thanks for all your help. _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
